3 mechanisms of microevolution - natural selection, genetic drift, gene flow 3 modifications made during RNA processing - - adenines added to poly-A tail - 5' end recieves a guanine cap - RNA splicing 3 steps of DNA replication - initiation, elongation, termination active transport - movement of molecules across a plasma membrane against from low concentration to high concentration with the expenditure of energy (ATP) by the cell adhesion - An attraction between molecules of different su...

• Where are electrons located? - electron cloud • Where are protons and neutrons located? - inside the nucleus 1) Cohesion - The intermolecular attraction between like molecules; such as the attraction of water molecules to each other. 10. Peroxisomes - contains enzymes that degrade toxins 2. Cellular Membrane - contains phospholipid bilayer, controls what goes in and out of the cell 3 different types of chemical bonds - ionic, covalent, hydrogen 3 Domains - Bacteria, Archaea, Eukarya...
